Want to pre arrange a ride to airport for 4 am tomorrow the app doesn't let me choose a time- how do i get time

In order to pre-arrange a ride you will need to book your ride through your desired company directly. Most services allow for pre-scheduled rides but not all, so first make sure the company you are using lets you book in advance. Both Uber and Lyft now let you book in advance through their applications.

Here are some help articles on booking Uber/Lyft in advance.
